Well i just received my order of Bat Guano 0-7-0 & Worm Castings 1-0-0. Wondering who has used such products and how was the, if any, success. When did you start using said products and in what quantity?
I use worm castings as a soil additive and top dressing. I used to brew tea but it was a pain to clean up afterwards. Worm castings are fantastic -- rich in nutrients yet very mild on plants. About 20% of my soil mix is worm castings. I also will spread a thin layer on the top of the soil once or twice during the grow, usually late in vegging and/or early in flowering.
